To all whom z't may concern:

Be it known that I, J osnrrr DAIN, a citizen of the United States, residing at Ottumwa, in the county of Wapello andState of Iowa, have invented certain new and useful Improvements in Gearing, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to gearing, and in.

the embodiment thereof illustrated in the accompanying drawings has particularly to do with the mechanism employed in motor vehicles for transmititngpower from the engine or motor to the traction wheels of the vehicle.

It also relates to transmission mechanism. of the type illustrated and described in my mediate disk which engages the two angu-' larly-disposed disks is driven by its engagement therewith and therefore may properly be termed the driven disk,-the angularly disposed disks being termed the drive disks. In the construction of my present invention the same general arrangement is employed, butin lieu of providing independent motors separately connected to the drive disks as in my said application, I provide for supplying power for the rota; tion of the drive disks by an intermediate drive disk which engages the angularly-disposed drive disks at the peripheries thereof so as to cause them to rotate in opposite directions and at an equal rate of speed. The intermediate drive disk may be driven by either a single or a multiple cylinder gasolene engine, by a steam engine, or by any other suitable motor. The intermediate disk is disposed relatively to the angular drive disks in much the same way as the driven disk except that it is not movable toward or from the centers of the drive disks and is somewhat larger in diameter than the driven disk so as to secure greater peripheral velocity, the peripheries of the angular drive disks being offset to compensate for the increased diameter of the intermediate drive disk. Both the intermediate drive disk and the driven disk are supported so as to be movable into or out of engagement with the inclined disks, and mechanism is provided by which when said disks are moved into engagement with said drive disks they are automatically pressed more tightly against those surfaces of the inclined drive disks respectively which are moving in such direction as to tend to throw the intermediate disks away therefrom, thus securing greater frictional engagement between them. In addition to the features above referred to, my present invention also includes various other improvements, which will be hereinafter particularly pointed out.

Referring to the drawings, which illustrate the chassis of a car, in which my improvements are embodied,Figure 1 is a plan View; Fig. 2 is a side elevation; Fig. 3 is a cross-section0n line 33 of Fig. 2 Fig. .4 is a sectional view of one of the angular drive disks; Fig. 5 is an enlarged detail, being a partial longitudinal section through the transmission mechanism; Fig. 6 is a cross-section on line 66 of Fig. 5; Fig. 7

is a partial section on line 77 of Fig. 5; and Fig. 8 is a sectional view of the front portion of the frame on line 88 of Fig. 1.

Referring to the drawings for a detailed description of my improvements as illustrated therein,9 indicates the frame of the chassis, which is designed to carry the carbody. 10 indicates the front axle, 11 the front wheels, 12 the rear axle, and 13 the rear wheels. It will be understood that these parts are of any well-known and approved construction, the front axle having any suitable construction of steering knuckles, etc.,

and the rear axle having the usual diiferential mechanism. The frame 9 is supported at its ends on front and rear springs l415 of any suitable type, and the outer end-portions of the rear axle 12 are pivotally connected by converging bars 16 with the front portion of the frame 9, as shown in Fig. 1.

17 indicates a pivot connecting the joined front ends of the bars 16 with the front portion of the frame 9, said frame'having a de pending arm 18 to receive said pivot, as shown in Fig. 8, so that the forward portion of the sub-frame formed by the bars 16 lies below the plane of the frame 9. The

rear ends of the bars 16 connect with the rear axle housing 19 substantially in line 'with the axle, as shown in Fig. 2, and said side bars 16, as shown in Fig. 1. The con- I struction and arrangement of the sub-frame and connected parts are not herein claimed as they form the subject of a separate application filed of even date herewith, Ser. No. 461,569.

21 indicates the crank-shaft of the motor, which, in the construction shown, is of the four-cylinder type of gasolene motor. Said crank-shaft extends longitudinally of the chassis, its front end-portion being journaled in a sleeve 22 carried by the sub frame above thepivot 17, as shown in Fig. 8. The rear end-portion of said crank-shaft is journaled in suitable hearings in a crossbar 23 secured to the sides of the frame 9 as shown in Fig. 1.

24 indicates the usual fly-wheel mounted on the rear end-portion of the crank-shaft.

25 indicates a drive-shaft, which extends longitudinally of the machine and is connected with the rear end-portion of the crank-shaft 21 by a universal connection 26 of any suitable type. At its rear end the driveshaft 25 carries a beveled drive-disk 27. Said shaft is ournaled in a sliding box 28 arranged to move up and down in an inclined plane in suitable ways provided in the housing 29 of the transmission mechanism. The box 28 and the manner in which it is mounted are best shown in Fig. 7, from an inspection of which it will be'seen that the box 28 slides in an inclined slot 30 provided in the housing 29 and is normally drawn downward by a spring 31. The purpose of this arrangement will hereinafter appear.

3233 indicate angularly-disposed drive disks, which are arranged opposite to each other on transverse shafts 34-35, respectively, suitably mounted on the machine frame. Said shafts are preferably journaled in lateral extensions 3637 of the housing 29, as best shown in Fig. 3, and are adjustable endwise by means of screws 3889 which bear against their outer ends, as shown in said figure. The drive disks 3233 are best set so that they are closest together at the bottom, as shown in Fig. 3, thus utilizing gravity to assist in normally holding the driven disk and the interme diate drive disk in engagement therewith. The angular drive disks are provided with offset peripheries, as shown at 40 in Fig. 3, the offset portion being beveled so as to properly engage the intermediate drive disk 27.

41 indicates the main transmission shaft,

- Fig. 1.

guides of the boxes 2843 are inclined in which extends longitudinally of the ma chine and is inclined upward toward its forward end, the latter being in line with the projected axes of the transverse shafts 34-35. The rear end of said transmission shaft 41 is connected by a universal connection 42 with a differential shaft 43, which connects with the differential in the rear axle housing 19. The forward portion of the shaft 41 is journalcd in a box 43 similar to the box 28 and slides up and down in an inclined plane in suitable guides formed by the transmission housing 29, as shown in It will be understood that the opposite directions.

. 44 indicates the driven disk, which is mounted upon the forward portion of the "shaft 41 I and is movable longitudinally thereon in a suitable key-way so that it rotates therewith. The disk 44 frictionally engages the inner faces of the inclined disks -32-33 and may be moved either forward or back of the centers thereof so as to drive the transmission shaft 41 in either direction. The purpose of mounting the boxes 28 and 48 in inclined guides as described is to pro vide for automatically pressing the disks 27 and 44 more tightly against those surfaces of the inclined drive disks which are moving in such direction as to tend to throw the intermediate disks away therefrom, thus securing greater frictional engagement between them. The speed of the shaft 41 may be regulated by varying the position of the disk 44 with reference to the centers'of the inclined disks 3233, and this rotation may be stopped altogether by moving the disk 44 into line with the centers of the disks 32-33. As best shown in Figs. 1 and 4, said disks 3233 are provided with recesses 45 at the centers so that when the disk 44 is in line with such centers it is out of, engagement with said disks.

It will thus be seen that the speed by which the transmission shaft may be driven may be accurately controlled without varying the speed of the inclined drive disks. If desired also the disk 44 may be moved entirely out of engagement wit-h the inclined drive disks, either by moving it into line with the centers thereof or by lifting it out of engagement with the inclined disks. The latter operation is accomplished by means of a foot-pedal 46 pivotally mounted at 47 on a suitable support having a depending arm 48 connected by a rod 49 with one arm of a bell-crank bell-crank lever 50 the box 43 may be moved vertically and the position of the transmission shaft 41 anddriven disk 44 adjusted accordingly. The intermediate drive disk 27 may also be moved out of engagement with the inclined disks, if desired, but it is seldom that it needs to be moved out of engagement therewith, and consequently mechanism for so moving it is not shown. A device similar to that shown for the disk let may be employed, if desired. In order to assist in holding the disk 27 in engagement with the inclined disks, the spring 31 is provided which is connected with the box 28 and with a fixed connection 55 attached to the housing 29, as shown in Fig. 5. A similar spring may be employed in connection with the box 43, if desired.

For moving the driven disk 44 upon the shaft 41 I preferably provide a fork 56 which engages a grooved collar 57 connected with the disk 44., said fork being carried by a rod 58 sliding in a sleeve 59 suitably supported on the frame of the machine. The rod 58 is moved longitudinally in the sleeve 59 by means of a lever 60 connected thereto by a rod 61. Said lever is suitably fulcrumed on the frame of the machine on an arm 62 secured to the crossbar 28, as shown in Figs. 1 and 5. The crank-shaft 21 is provided with the usual hand-crank 63 for starting the engine.

l/Vhile my improved transmission is designed particularly for motor vehicles, it will be understood that it is well adapted for other uses, and my invention, therefore, is not restricted to its use in a motor vehicle, but includes all other uses to which it may be put, and the claims hereinafter made are to be construed accordingly. It will be understood also that while the best results are secured by setting the drive disks so that the lowest points in their peripheries are closest together, they may be otherwise arranged, generically considered, and my in vention is not restricted to placing them in the manner shown in the drawings, except in so far as that arrangement is particularly claimed.
